Xcode: Mac OS X build fixed

I was originally going to split this up into multiple patches, but
the Xcode project file format is a bit difficult to cleanly split
for patching. So anyway, I've made a few changes:

 - Fixed Xcode 3.2 compatibility (complaints about using GCC
   4.2 with the Mac OS X 10.4 SDK, among other things).
 - Removed the tilegen target (this is now done via a script)
 - Fixed the Crawl-tiles-cmd target
   + Now links to AppKit.framework and OpenGL.framework
   + Set the search path for the  SDL, SDL_image and libpng
     frameworks to be /Library/Frameworks, which is standard.
 - Fixed the Crawl target
   + Now copies the necessary non-standard frameworks to the
     Frameworks directory (this eliminates the dependency on
     Fink).
   + Eliminated a couple redundant or worthless steps which
     did things we really didn't need.
 - Added precompiled header support to the Crawl-cmd and
   Crawl-tiles-cmd targets.
